Orchard Management Practices and Handbook
The purpose of this project was to develop an SAE start-up handbook for the Hollister FFA program\u27s orchard. The orchard was being underutilized by the chapter and the hopes are that the chapter will supply students with this handbook allowing for a more diverse group of SAE projects within the chapter. Implementing the steps outlined in this handbook would also create a more competitive chapter in the areas of proficiencies and degrees
On the polytropic Bondi accretion in two-component galaxy models with a central massive BH
In many investigations involving accretion on a central point mass, ranging from observational studies to cosmological
simulations, including semi-analytical modelling, the classical Bondi accretion theory is the standard tool widely adopted.
Previous works generalized the theory to include the effects of the gravitational field of the galaxy hosting a central black hole
and of electron scattering in the optically thin limit. Here, we apply this extended Bondi problem, in the general polytropic case,
to a class of new two-component galaxy models recently presented. In these models, a Jaffe stellar density profile is embedded in
a dark matter halo such that the total density distribution follows a r−3 profile at large radii; the stellar dynamical quantities can
be expressed in a fully analytical way. The hydrodynamical properties of the flow are set by imposing that the gas temperature at
infinity is proportional to the virial temperature of the stellar component. The isothermal and adiabatic (monoatomic) cases can be
solved analytically; in the other cases, we explore the accretion solution numerically. As non-adiabatic accretion inevitably leads
to an exchange of heat with the ambient, we also discuss some important thermodynamical properties of the polytropic Bondi
accretion and provide the expressions needed to compute the amount of heat exchanged with the environment as a function of
radius. The results can be useful for the subgrid treatment of accretion in numerical simulations, as well as for the interpretation
of observational dat
Implementation of eco-sustainable biocomposite materials reinforced by optimized agave fibers
Although several works have recently been published in literature about biocomposites, i.e. about composites with polymeric matrix reinforced by natural fibers, only a few articles have been devoted to the implementation of high performance biocomposites for structural and semi-structural applications. The present study aims to give a contribution by considering biocomposites obtained by using an eco-friendly partially bio-based epoxy (green epoxy) and sisal (agave sisalana fibers) obtained by a proper optimization process.
Through a systematic experimental analysis, three different types of biocomposites obtained with a suitable manufacturing process, such as random short fiber biocomposites, random discontinuous fibers biocomposite obtained through the preliminary manufacture of MAT fabrics, and unidirectional long fibers biocomposites obtained through the preliminary manufacture of unidirectional \u201cstitched\u201d fabrics, have been studied
Pregnancy in immigrant women
Objective: We wanted to study how foreign women face pregnancy and childbirth in a society quite different from their own. Methods: In 2004 we studied 328 pregnant women at the Department of Gynaecology at the "General Hospital Umberto 1" in Rome. Information on patients' personal lives and experiences was collected. Results: Women were classified into six (6) groups based on nationality, race, religion and culture. Conclusions: Arabian women had the most natural childbirths. African women had a longer duration of gestation. Women from Eastern Europe underwent frequent tests and examinations, but had the highest chance of having preterm births. Chinese women did not usually undergo many examinations and were able to tolerate pain during childbirth quite well
